Title: Improvements in, or relating to, visual signalling means for cash registers and similar accounting machines
IPC: G06C11/02
Filed: 1948-09-21
Abstract: 653,146. Cash registers &c. CENTRE D'ETUDES M.B.A. (MECANIQUE BALISTIQUE ARMEMENT). Sept. 21, 1948, No. 24652. Convention date, Oct. 31, 1947. [Class 106 (i)] The indicator of a cash register or like accounting machine comprises, for each denominational order, a plurality of superposed thin yielding blades 1 of different lengths, the inner ends of which are fixed at 3 and the outer ends 61 are free and adapted to be engaged by gates 6 in movable selecting members 5 the position of which is defined by the registering or recording mechanism and which select the number of blades allowed to rise to the iridicating position when a bar 20 retaining the blades in folded position is released. The registering &c. mechanism sets a stepped wheel 17 in accordance with the amount to be indicated and drives a pinion 31 which through gear 32 and toothed sector 34 operates bar 20 to fold back all the blades 1 and locks this bar by a stud 24 engaging a projection 24 on an arm 23. The selecting members 5 are all moved forwardly to release the ends of the blades 1 in the gates 6 by a cam 36 rocking a bar 43 engaging flanges 7 on the rear ends of the selecting members which also rock levers 10 away from the stepped wheels 17. A bar 52 common to all the levers 10 holds them in this position. When the teeth of the wheel 31 leave those of the wheel 32 a cam 44 is in position to allow a roller 47 to enter a recess 45 of the cam, rocking a lever 48 and releasing the bar 52 so that the levers 10 are urged by springs 27 to contact by their projections 16 the stepped wheels 19. The ends 9 of the levers urge the selecting members 5 rearwardly so that each selecting member takes up a position depending on the digit recorded. A boss 46 on the cam 44 then causes rocking of the lever 48 in the opposite direction and a projection 53 on bar 52 depresses the lever 23 to release stud 24<SP>1</SP>, thus freeing the rod 20 and allowing those blades 1 that are not held back by the selecting members 5 to rise along with the bar 20 which is then housed in a recess in a plate 31.

Title: Regulating the feed of forced through-flow steam generators
IPC: F22B29/08
Filed: 1959-07-17
Abstract: 923,610. Feedwater supply systems for steam boilers. SULZER FRERES S.A. July 17, 1959 [July 18, 1958; May 27, 1959], No. 24660/59. Class 123 (2). The rate of feedwater supply to a forcedflow, once-through steam boiler comprising a preheater 104 into which feedwater is supplied by a pump 100 through a feed regulator 103, an evaporator 105, a separator 106 and a superheater 108 is controlled by a temperature signal picked-off at the end of a throttled evaporator tube and modified by a signal representing the wetness of the steam at the entry to the separator. The latter signal which is derived from the ratio of the rate at which water is separated out to the rate of steam flow into the superheater or, in a modification, to the rate at which feedwater is fed in, may be integrated with a signal representative of steam output. Thus in Fig. 1, a flow meter 107 inserted between the separator and superheater transmits a signal representative of steam flow to an integrating unit 116. The unit is connected to a proportional regulator 112 controlling the separator drain valve 113 so that the amount of water drained off per unit time is a function of the load. On the separator there is a transmitter 111 responsive to the level of water therein and from which a signal line leads to the regulator 112. From the regulator 112 is signal representative of the wetness of the steam and formed from the ratio of water drained off per unit time and the rate of steam flow at the superheater inlet passes to a regulator 110 which has a proportional and integral characteristic to modify a signal representative of temperature at the end of a throttled pilot tube of the vaporizing section 105 transmitted to the regulator 110 from a temperature pick-off 109. The modified signal is transmitted through a line 142 to an adjusting device 119 of the feed regulator valve 103. Under constant load the steam wetness remains constant; consequently the temperature signal from the pick-ofF 109 is not modified and the feed regulator opening remains steady. In the case of increasing load, however, more unevaporated water passes into the separator and the water level regulation system thereof provides for a larger amount to be withdrawn in unit time, thus changing the ratio of said amount and the steam flow, whereupon the unit 116 increases the temperature required value in the regulator 110 to modify the signal from the pick-off 109 and adjust the feed regulator setting until the temperature at the end of the evaporator corresponds to the new load. Since the adjustment of the required temperature in dependence on the steam wetness will not respond sufficiently quickly in the event of a sudden variation of load a pre-signal of the change in steam flow is transmitted from the meter 107 through a line 148, 149 to act immediately on the feed regulator 103 by summation with the output signal of the regulator 110. Specification 698,788 is referred to.

IPC: C10K1/12
Filed: 1925-10-08
Abstract: 250,837. Coulier, S. Oct. 8, 1925. Materials for purifying gas; purifier waste, revivifying.-In a process for the purification of fuel gases from hydrogen sulphide, hydrocyanic acid, &c. by absorption in an alkaline solution containing or subsequently mixed with an iron compound, the solution after precipitation of the iron sulphide is treated with an iron compound in the presence of carbon dioxide or a carbonated iron compound to precipitate iron ferrocyanide which is separated before regenerating the solution by aeration. The carbon dioxide formed by the aeration is re-utilized for further purification. The gases are passed up a column 1 down which flows a solution of sodium carbonate. The fouled solution is led through a pipe 2 into a mixer 3 where it is mixed with ferrous hydrate paste, and the mixture is passed to a decanter 5 where the iron sulphide is separated. The solution is then treated in a mixer 7 with ferric carbonate and the mixture is led into a washer 10 where it is treated with carbon dioxide the product being removed to a decanter 12 where the ferrocyanide is precipitated as a sludge which is filtered on a rotary filter 14 the filtrate being added to the decanter solution which is pumped to a tower 19 for revivification, the carbon dioxide produced being used in the washer 10.

Title: Improvements in ratchet and friction pawls employed in rotating ratchet or friction driven wheels
IPC: F16D41/10
Filed: 1925-10-13
Abstract: 261,159. Adams, M. H. Oct. 13, 1925. Reversing-gearing.-Ratchet gearing, particularly for driving rotary screens for liquids, is so arranged that if the driven member becomes locked, the driving-pawl will yield and pass without injury to the opposite side of its actuating- arm. A drum 1, Fig. 1, is driven by a friction slipper 2 pivoted at 8 to a frame 9, pivoted at the axis of the drum. The pivot 8 can slide in a slot 5<1> in a tube 5 containing a spring 6 engaging a sliding block 7 through which the pivot passes, so that, if the drum cannot be driven, the slipper 2 will yield and pass harmlessly to the opposite side of the frame 9. A detent prevents backward movement of the drum. Instead of acting directly on the pawls, the springs 6 may be placed in the arms 9, which are in two parts capable of yielding telescopically. Fig. 8 shows a positive driving pawl 5<a> engaging teeth 1<a> on the drum. By arranging stops to limit the rotation of the drum in both directions, the device is adapted to act to reverse the rotation automatically. When a stop is encountered the pawl passes to the opposite side of its actuating-arm and then proceeds to drive the drum in the opposite direction.

Title: Improvements in and relating to radio receiver systems
IPC: H04B7/08
Filed: 1947-09-19
Abstract: 627,468. Radio receiving systems. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. Sept. 19, 1947, No. 25566. [Class 40 (v)] In a system in which the output of two or more radio receivers is combined, the gain of an amplifying stage in each receiver is varied inversely as the amplitude of noise voltages located in a frequency band outside that occupied by the desired signal. The arrangement improves the signal to noise ratio of the combined output. in a system involving a master station and a mobile station in which satellite stations may relay signals from the mobile station to the master station over an auxiliary link, the various signals received at the master station then having different signal to noise ratios. Energy from receiver 10 in the Figure is supplied to a filter 15, which may be of the type described in Specification 611,841, which supplies two outputs corresponding to different audio frequency bands. Energy from one frequency band which covers speech signals is applied via potentiometer 19 to variable-run amplifying valve 11. Energy from the other frequency band containing noise, is applied to diode 13 to supply a variable negative bias to the control grid of valve 11. The arrangement is based on the fact that noise voltages cover substantially the whole audio-frequency spectrum, and also that noise voltages tend to decrease as signal voltages increase. Two other similar channels comprising receivers 10<1> and 10<11> are also provided, the output being combined at terminal 12; Should the amplitude of the incoming signals to one of the receivers fall, with consequent increase in the noise voltages, the gain of the associated valve 11 is reduced, falling if necessary to zero, so that the signal to noise ratio of the combined output is not impaired.
